Pinaka 817 HT-400
Pinaka 817 HT-400 is a high-performance, single-component silicone co-polymer coating engineered for thermal insulation and heat-resistant protection up to 400°C. Formulated with ceramic microspheres and reflective silicone resin, it reduces radiant and convective heat loss, lowering surface temperatures by 5–10°C and enabling significant energy savings. The coating delivers excellent adhesion, high emissivity, and long-term stability under continuous thermal exposure. Its self-priming property simplifies application across boilers, ducts, furnaces, and heat-prone industrial installations.
Available Packs: 4L, 20L
